Homework Help Overview

The problem involves calculating the weight of an unknown object using torque principles. A pole of known weight and length is balanced with the unknown weight at one end, and the setup includes specific distances from the center of gravity.

Discussion Character

  • Exploratory, Assumption checking, Problem interpretation

Approaches and Questions Raised

  • Participants discuss the application of torque equations and the balance of moments. There is an attempt to clarify the positioning of the unknown weight relative to the pole's center of gravity.

Discussion Status

Some participants have offered calculations based on their interpretations of the problem setup. There is an acknowledgment of the original poster's urgency for assistance, and some engagement with the problem has occurred, though no consensus has been reached.

Contextual Notes

The original poster expresses concern about an upcoming exam, indicating a time constraint that may affect the depth of discussion. There is also a note of emotional appeal for help, which may influence the tone of the responses.

Homework Statement


Torque is used to determine the weight of an object. A 10.0 m long pole weighing 20.0 N has its center of gravity 2.00 m from one end. An object of unknown weight is hung at the end opposite the center of gravity. With the object hanging at this end, the pole now balances 2.00 m from the unknown weight. What is the weight of the unknown weight? Ans:60.0


Homework Equations


T = F * R


The Attempt at a Solution


T = 20 * 2
= 40 ?

oh please anyone? my exams tommorow? I am sorry for being so naggy? any help AT ALL will be great. anything. I've been staring at this screen refreshing every 5 seconds.
 
PLeASE IM BeGGING YoUUUUUUUUUUUUUUUUUUUUUUUUUU
 
Ok let me have a crack at it.I assume that unknown object is at the other end of stick (not the center of gravity end). So

Tcw = Tccw
2*X = 6*20
X=60 N
 
Thank you so much. So, SO much. I love you. In a non-gay way. <3
